hi all

please give the solution for this without using session and application...

In test1.jsp file
i am setting values for my setter methods using <jsp:usebean> <jsp:setproperty> tags as shown below.

After that i am adding the usebean object to array list, then using request.setAttribute("arraylist object")

<jsp:useBean id="payment" class="com.common.PaymentHandler" scope="request" />

<jsp:setProperty name="payment" property="strCreditCardNo" param="creditCardNumber" />
<%-- <jsp:setProperty name="payment" property="iCsc" param="securityCode" /> --%>
<jsp:setProperty name="payment" property="strDate" param="expirationDate" />
<jsp:setProperty name="payment" property="strCardType" param="creditCardType" />
<%--<jsp:setProperty name="payment" property="cDeactivate" param="deactivateBox" />
<jsp:setProperty name="payment" property="fAmount" param="depositAmt" />
<jsp:setProperty name="payment" property="fAmount" param="totalAmtDue" /> --%>

<jsp:useBean id="lis" class="java.util.ArrayList" scope="request">

Do you have any form in your page?
Are you using submit button to submit the request to the servlet?

Please read about request lifecycle.

[edited after googling around]

I tried to get some link on it for a while. But no success. So, just take this statement.

When you request to servlet by submitting a page via html submit button or javascript submit function then it would be a brand new request. The old request object will be vanished.

The JSP is generally the last component in the request chain.
As Adeel mentioned, this is not the place to add things to a request object unless you are forwarding back to the servlet again before sending the output to the browser.
